Definitions

  • the invention relates to a valve for a door closer or electrohydraulic door drive, which is acted upon by a piston arranged in a cylinder of the door closer or door drive, wherein the valve pin of the valve has a valve cone which can be adjusted against a valve seat and by means of an external thread arranged on the valve pin is screwed with an inner thread arranged on the cylinder or housing of the door closer, with a sealing ring sealing the valve pin against a pressure-free space, on the side of the valve pin opposite the valve cone, in a circular groove of the valve pin.
  • a multifunctional valve which on the one hand can act as an overcurrent or pressure relief valve with adjustable counter-holding or static locking force and, on the other hand, as a throttle valve with adjustable flow resistance.
  • the previously known valve is screwed by means of an external thread into a cylinder ei ⁇ nes door closer.
  • valves against a non-pressurized space are usually carried out by a ange ⁇ in a groove of the valve or the valve pin, the cylinder or housing of the door closer fitting O-ring seal.
  • an O-ring seal generally prevents inadvertent locking of the valve due to undesired adjustment of the screw connection between valve and cylinder or housing.
  • At high stress of the valve ie when sudden high pressures occur, especially after a prolonged period of operation, but latches of the valve, which affect a faulty ⁇ réelles ⁇ or closing function of the door, the cause of which are determined only by a costly review of the entire door closer can.
  • the object of the invention is to find a technically simple, cost-effective and reliable solution that verhin ⁇ a locking of the valve by adjusting the screw between the valve on the one hand and the cylinder or housing of a door closer on the other hand under load of the valve by sudden high pressures changed.
  • the invention solves the problem with the teaching of claim 1.
  • the function of the O-ring seal can be reduced to a pure sealing function, while an inventive rotation lock is designed such that it exclusively rotates the external thread of the valve with respect to the internal thread of the cylinder or the housing of the valve Door closer and thus prevents Verrie ⁇ rules of the valve.
  • ange ⁇ At the end of the valve pin, following the circular groove, a second, at least one tangent to the circumference of the valve pin Surface having groove ange ⁇ for receiving an anti-rotation is ange ⁇ .
  • the aforesaid groove thus delimits a square or rectangular cross-section of the valve pin due to the surfaces of the groove base running tangentially to the circumference of the valve pin.
  • the anti-twist device itself consists of a plastic ring that can be inserted into the groove and abuts by means of a predetermined pretensioning of a blind bore of the cylinder or of the housing.
  • the limited elastic plastic ring can als ⁇ reason of a predeterminable oversize with a sufficient An ⁇ pressing force of the stepped bore of the cylinder or the housing abut and thus reliably prevent locking of the valve.
  • the plastic ring Since the blind bore is a circular bore in a known manner, the plastic ring has a circular outer contour and an inner contour corresponding to the square or rectangular cross section of the valve pin and is advantageously designed as a ring open on one side, so that in front of Mounting no over-buttoning of the plastic ring on the associated groove, but only a lateral Koch ⁇ push is required.
